As mentioned by karthic_arp --Not a good idea still if you want it you can do this way
DECLARE
CURSOR C
IS
SELECT DISTINCT security_id
FROM security_xref
WHERE security_alias_type IN ('BADSYMBOL', 'ERRORSYMBOL', 'BADCUSIP', 'ERRORCUSIP' );
-Counter to count records
counter number(4) default 0;
BEGIN
FOR rec in C
Loop
UPDATE security SET display_security_alias = CONCAT ('BAD_ALIAS_', display_security_alias)
WHERE security_id = rec.security_id
counter := counter +SQL%rowcount ;
If counter >= 500 then
counter := 0;
commit;
end if;
END Loop;
end ;
/NOT tested.Apart from committing every N rows, being a completely technically stupid idea, committing inside a cursor loop just take it one step further to stupiddom.
